Yesterday the temperature was 6°C. Today it is -5°C. In degrees Celsius, what
is the change in temperature?

Answer:

(a) 17/20 b.5/18/25 c. 1.255

The outlier of the data is 14.16 gram

An outlier is a data point in statistics that dramatically deviates from other observations. An outlier may reflect measurement variability or it may point to an experimental error; the latter is occasionally removed from the data set. In statistical analyses, an outlier can result in significant issues.

Given:

Weights of the samples are 13 g, 14 g, 23 g, 11 g, 15 g, 14 g, 14 g, 12 g, 13 g, 15 g, 14 g, and 12 g.

So, the outlier is

= 13 x 2 + 14 x 4 + 12 x 2 + 11 + 15 x 2+ 13 / 12

= 170 gram /12

= 14.16 gram.

Hence, the outlier of the data is 14.16 gram

Answer:

(x) ∠CAB

Step-by-step explanation:

In ΔCOD and ΔBOA

\(\frac{OA}{OB} = \frac{OD}{OC} \\\\\implies \frac{OC}{OB} = \frac{OD}{OA}\)

Also,

∠COD = ∠BOA (vertically opposite angles)

⇒ ΔCOD and ΔBOA are similar

⇒ ∠CDO = ∠BAO

⇒ ∠CDB = ∠BAC

⇒ ∠CDB = ∠CAB

Answer:

(6, ....... )  ( -3, .........)  ( 1, .......)

x,y values therefore = (6, 29) ( -3, -34) (1, -6)

as x = 0 when y = -13

we simply x 6 into equation to find 30

y = 7 x 6 -13

y = 42 - 13

y = 29  

Then for -3 we simply x by -3 to find y

y = 7 x -3 -13

y = -21 - 13

y = -34

then for 1 we simply x by 1 to find y

y = 7 x 1 -13

y = 7 - 13

y = -6

y = 7x - 13

Step 1)  Set above equation equal to 0 by remembering the methods;

Solve   y-7x+13  = 0

Step 2)  Calculate the y intercept;

Notice that when x = 0 the value of y is -13/1 so this line "cuts" the y axis at y=-13.00000   see attached to help memorize.

Step 3) Calculate the X-Intercept :

When y = 0 the value of x is 13/7 Our line therefore "cuts" the x axis at x= 1.85714

Step 4) Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -13.000 and for x=2.000, the value of y is 1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 1.000 - (-13.000) = 14.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = 14.000/2.000 =  7.000

As seen below.

 x-intercept = 13/7  =  1.85714

slope =  14000/2000 = 7000

x intercept =  13/7 = 1.85714

y intercept = 13/1 = 13.00000

The two numbers that add up to 18 and have the maximum product are 9 and 9.

We want to find two numbers that add up to 18 and that have the maximum product.

If the two numbers are X and Y:

The product is P = X*Y

And the sum must be:

X + Y = 18

Then we can write:

X = 18 - Y

Replacing that in the product we will get:

P = (Y - 18)*Y

So we have a quadratic.

Notice that the zeros are at  Y = 0 and Y = 18, then the maximum is at the vertex Y = (0 + 18)/2 = 9

Then the value of X must be:

X = 18 - 9 = 18 - 9 = 9

The two values are 9.

The Propositions are resulting

(a) ∀x∃y(x = y²) is False

(b) ∀x∃y(x² = y) is True.

(c) ∃x∀y(xy = 0) is True.

(d) ∀x∃y(x + y = 1) is True.

(a) ∀x∃y(x = y²)

This proposition states that for every x, there exists a y such that x is equal to y². To determine the truth value, we need to check if this statement holds true for every value of x.

If we take any positive value for x, we can find a corresponding value of y that satisfies the equation.

For example, if x = 4, then y = 2 satisfies the equation since 4 = 2². Similarly, if x = 9, then y = 3 satisfies the equation since 9 = 3².

Therefore, the proposition (a) is false.

(b) ∀x∃y(x² = y)

For any given positive or negative value of x, we can find a corresponding value of y that satisfies the equation.

For example, if x = 4, then y = 2 satisfies the equation since 4² = 2. Similarly, if x = -4, then y = -2 satisfies the equation since (-4)² = -2.

Therefore, the proposition (b) is true.

(c) ∃x∀y(xy = 0)

The equation xy = 0 can only be satisfied if x = 0, regardless of the value of y. Therefore, there exists an x (x = 0) that makes the equation true for every y.

Therefore, the proposition (c) is true.

(d) ∀x∃y(x + y = 1)

To determine the truth value, we need to check if this statement holds true for every value of x.

If we take any value of x, we can find a corresponding value of y that satisfies the equation.

For example, if x = 2, then y = -1 satisfies the equation since 2 + (-1) = 1. Similarly, if x = 0, then y = 1 satisfies the equation since 0 + 1 = 1.

Therefore, the proposition (d) is true.

Answer:

t = 20°

Step-by-step explanation:

Recall that the base angles of an isosceles ∆ are equal to each other.

This means that:

<NMO and <NOM of ∆MNO are congruent to each other.

Thus,

m<NMO = ½(180 - m<N) = ½(180 - 70)

m<NMO = ½(110)

m<NMO = 55°

Also, <PMO and <POM are congruent to each other. Thus:

m<PMO = ½(180 - m<P) = ½(180 - 110)

m<PMO = ½(70)

m<PMO = 35°

Therefore,

m<NMO = t + m<PMO (angle addition postulate)

55° = t + 35° (substitution)

Subtract 35 from each side

55° - 35° = t

20° = t

t = 20°

the volume of Alice's chicken coop in cubic meters is approximately 21.46 m³.

what is volume ?

Volume refers to the amount of space that an object or substance occupies in three-dimensional space. It is typically measured in cubic units, such as cubic meters (m³) or cubic feet (ft³), and is calculated by multiplying the length, width, and height of the object

In the given question,

To convert 758 cubic feet to cubic meters, we need to use the conversion factor:

1 ft³ = 0.3048³ m³

We can then multiply the volume in cubic feet by this conversion factor to get the volume in cubic meters:

758 ft³ × (0.3048 m/ft)³ = 21.46 m³ (rounded to two decimal places)

Therefore, the volume of Alice's chicken coop in cubic meters is approximately 21.46 m³.

After 6 years, Zandile earns an interest of rupees 608.9 after investing her Christmas bonus for R 875.00 in a bank that offers interest rates of 9% p.a. compounded half-yearly.

The simplest way to calculate interest is as a percentage of the principal. For instance, if you agreed to borrow $100 from a friend with 5% interest, the interest you would pay would only be 5% of $100: $100(0.05) = $5.

Compound interest is when an amount receives interest on top of it each time interest is paid on the original amount. The principal (original) sum and the interest that has already accrued over the course of previous periods are used to calculate compound interest.

Here,

Principal amount= 875

Rate of interest= 9% pa

Compounding= half-yearly (2/year)

Time= 6 years

A = P(1 + r/n)ⁿᵇ

A=final amount

P=initial principal balance

r=interest rate

n=number of times interest applied per time period

b=number of time periods elapsed

A=875(1+9/6)⁶*²

A=₹1,483.90

Zandile invests her Christmas bonus of R 875.00 in a bank that offers interest rates of 9% per year compounded semi-annually, and after 6 years, she earns an interest of Rs 608.99.

When x = 13, the equation that is true is option D) 5(x - 9) = 20.

To determine which equation is true when x = 13, we can substitute the value of x into each equation and see which equation holds true. Let's go through each option:

A) 3(18 - x) = 67

Substituting x = 13:

3(18 - 13) = 67

3(5) = 67

15 = 67

The equation is not true when x = 13. Therefore, option A is false.

B) 4(9x) = 23

Substituting x = 13:

4(9*13) = 23

4(117) = 23

468 = 23

Again, the equation is not true when x = 13. Therefore, option B is also false.

C) 2(x - 3) = 7

Substituting x = 13:

2(13 - 3) = 7

2(10) = 7

20 = 7

Once again, the equation is not true when x = 13. Therefore, option C is false as well.

D) 5(x - 9) = 20

Substituting x = 13:

5(13 - 9) = 20

5(4) = 20

20 = 20

Finally, the equation is true when x = 13. Therefore, option D is true.

Answer:

(-7)+(-2)

Step-by-step explanation:

Which other expression has the same value as (-7) – 2?

The expression given :

(-7) – 2 = - 7 - 2 = - 9

To obtain our answer, we find the result of the expressions given in the option :

(-7)+2 = - 7 + 2 = - 5

7- (-2) = 7 - - 2 = 7 + 2 = 9

7+(-2) = 7 - 2 = 5

(-7)+(-2) = - 7 + - 2 = - 7 - 2 = - 9

Given,

AX\((D+BX)^{-1}\) = C

Multiply both sides on the right by (D+BX):

AX\((D+BX)^{-1}\) × (D+BX) = C × (D+BX)

AX (\((D+BX)^{-1}\) (D+BX)) = C(D+BX)

AX × I = CD + CBX

AX = CD + CBX

Subtract CBX on both sides and factor:

AX – CBX = (CD + CBX) – CBX

AX – CBX = CD + (CBX – CBX)

AX – CBX = CD + 0
